[SOLVED] Nouveau HDMI audio

fr19k · 12-25-2013, 04:54 PM

Hello

I'm trying to redirect audio from my notebook(asus 1215n) to TV Set via HDMI, but only image is working correctly(1080p).
aplay -l doesn't show me any outputs related with nvidia ion card, only HDA intel.
In alsamixer i don't have a SPDIF control.
Nouveau site shows that it is possible to playing audio via HDMI.

What i should do, to get audio via HDMI?

Slackware current, Kernel 3.13rc5, Mesa 10.0.1, Alsa 10.0.27.1, xorg 1.14.3, xf86-video-nouveau 1.0.10(git), xf86-video-intel 2.99.906(git), Direct Rendering are working on intel & nouveau
NVIDIA Corporation GT218 [ION 2]

These ASUS netbooks are a bit buggy with HDMI audio. Create a file that ends in .conf in '/lib/modprobe.d'. For example I create a file at '/lib/modprobe.d/sound.conf' with the following:

Code:

options snd-hda-intel probe_mask=0xffff,0xfff2

That should fix the card detection and SPDIF in alsamixer. This may require you to 'rmmod snd-hda-intel' and then modprobe it back in, or just reboot.

The other part of the puzzle involves telling programs to redirect the audio to a specific sound card. Most are able to do this.

Unfortunately, it doesn't work for me ..
The SPDIF control still does not appear. In /var/log/dmesg i see errors after adding options for snd-hda-intel

Code:

[  523.998024] hda-intel 0000:00:1b.0: Codec #1 probe error; disabling it...
[  525.004020] hda-intel 0000:00:1b.0: Codec #2 probe error; disabling it...
[  526.010021] hda-intel 0000:00:1b.0: Codec #3 probe error; disabling it...

My notebook is Asus EeePC 1215n, maybe there are differences between EeePC & 'pure' Asus

The full name of HDA intel soundcard is Realtek ALC269VB. In alsamixer in 'capture' section i can see a 'Digital' control, but not in playback

Can you post the output of 'aplay -l'.

Drakeo · 12-26-2013, 02:07 PM

could you tell us what desktop you are using being it kde or xfce4 etc ,etc
when building new kernels and I have alsa problems I remove the /var/lib/alsa/asound.state
if using kde you need to remove the ~/.kde/share/config/kmixrc and kmixctrlrc
then reboot.
this causes alsa to probe your hardware and firmware.
! it is important at this point not to have any /etc/modprobe.d/snd-conf at the time.
this is so you can start your trouble shoot.

i'm using KDE 4.10.5 x86_64. I tried to remove asound.state from /var/lib/alsa & kmix* files but the SPDIF control is still unavailable

Make sure you have CONFIG_SND_HDA_CODEC_HDMI enabled in the kernel. I would just enable all the Intel HD audio codecs.

If it still is not detected then you can try the nvidia blob driver. Otherwise, I'm not sure it will work.

If it is detected but is multiple versions are detected then see:

Drakeo · 12-26-2013, 10:48 PM

ok now this should help you if you did build the configure the kernel correctly. Lot of hard work went into this.

All HDA codecs are included to the kernel module.

Code:

CONFIG_SND_HDA_INTEL=m
CONFIG_SND_HDA_PREALLOC_SIZE=64
CONFIG_SND_HDA_HWDEP=y
CONFIG_SND_HDA_RECONFIG=y
# CONFIG_SND_HDA_INPUT_BEEP is not set
CONFIG_SND_HDA_INPUT_JACK=y
CONFIG_SND_HDA_PATCH_LOADER=y
CONFIG_SND_HDA_CODEC_REALTEK=y
CONFIG_SND_HDA_CODEC_ANALOG=y
CONFIG_SND_HDA_CODEC_SIGMATEL=y
CONFIG_SND_HDA_CODEC_VIA=y
CONFIG_SND_HDA_CODEC_HDMI=y
CONFIG_SND_HDA_I915=y
CONFIG_SND_HDA_CODEC_CIRRUS=y
CONFIG_SND_HDA_CODEC_CONEXANT=y
CONFIG_SND_HDA_CODEC_CA0110=y
CONFIG_SND_HDA_CODEC_CA0132=y
# CONFIG_SND_HDA_CODEC_CA0132_DSP is not set
CONFIG_SND_HDA_CODEC_CMEDIA=y
CONFIG_SND_HDA_CODEC_SI3054=y
CONFIG_SND_HDA_GENERIC=y
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=10

I tried to change model in snd-hda-intel but SPDIF is still unavailable.

Drakeo · 12-28-2013, 06:10 AM

it seems the i2c_dev is not linking up to that or for some reason in that kernel models drm,i2c_dev,i2c_piix4,nvidia,videodev are not being read.
are they loaded ?. if the are then we may have an alsa problem in that kernel.

fr19k · 12-29-2013, 07:16 AM

i2c_drivers are loaded

In past i tried to use original nvidia driver. Hdmi device was present in aplay -L but i could not to play anything via HDMI, in additionaly it very often caused system hangs. Performance was very poor beacuse i don't wanted to lose GLX in Intel card. In this kernel 3.13rc5 nouveau works nicely and performance in glxspheres is (in Full HD resolution)

Code:

89.350912 frames/sec - 181.846975 Mpixels/sec

in compare to intel(i915) 1366x768

Code:

Only sound doesn't work..
After modprobe nouveau in /vr/log/dmesg i can see these messages

I deal with this problem!

. The reason for unavailable SPDIF control is switching on the notebook by regular power switch. I don't why, but when I switch on the notebook by "ExpressGate" button, then will HDA NVIDIA device present

Code:

05:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1)

cards i alsamixer

Code:

root@laptek:/var/log# cat /proc/asound/cards 
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xf5bf8000 irq 22
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xfbffc000 irq 17

aplay -L

Code:

hdmi:CARD=NVidia,DEV=0
    HDA NVidia, HDMI 0u
    HDMI Audio Output

In kernel configuration i set CONFIG_VGA_SWITCHEROO to "N" or "is not set", beacuse after modprobe nouveau, system hangs after several seconds.

metaschima · 12-31-2013, 11:34 AM

Maybe it is a BIOS setting that is doing it. Make sure HDMI audio is enabled there.

fr19k · 01-01-2014, 08:24 AM

Unfortunately, the bios in the Asus 1215N does not have any options for HDMI..
